- an Ancient Greek doctor
- His ideas and books were very influential well into medieval times and beyond
- He dismissed the idea that gods caused disease --> believed there was a physical reason for illness, which needed a physical cure
- Most of his treatments were based on diet, exercise and rest but he also used bleeding and purging
to get rid of excess humours
- He wrote the Hippocratic Oath, where doctors swore to respect life and prevent harm
- His method of clinical observation - studying symptoms, making notes, comparing with similar cases, then diagnosing and treating --> is the basis of the approach used today.
